“The Archbishop of Westminster had an unfettered discretion to appoint who he wished as a foundation governor of a Roman Catholic school in his diocese provided the School Governance (Constitution) (England) Regulations 2007 were complied with, and that included appointing his diocesan director of education as a governor at the school. The requirement in regulation 18 that two of the foundation governors should at the time of their appointment be eligible for election or appointment as parent governors was fulfilled by the presence on the existing governing body of two foundation governors who had been so eligible when they were appointed.”
